I've been scouring all the great info on this site for several weeks, ever since I was offered a Crown Graphic from my dad the antiques dealer. Thanks to this site, I was able to say yes and know that I would have access to the info to get things working. It has been a real blast learning about these cameras, I am really hooked!

As a thank you, I'd like to make a contribution to the body of information on accessories - namely filters. The Speed Graphic FAQ says use the Series VI Filter Kit, but what does that mean to a newbie? Which size adapter ring fits your lens? Which lenses take which series of filter?

My proposal is to build a table of the various lenses used by Graflex.org members, and list the Series and adapter ring size needed for each lens. I would be more than happy to compile the data & keep it updated,
but how to get everyone to cough up their filter/adapter info?

Any suggestions /comments would be appreciated. Thanks for considering!

Some of this info for the Optar lenses has already been compiled on the board: see http://www.oresteen.com/optar_lens.htm . Also use the Search feature on the board; enter "filter sizes" to get a long list of relevant threads.

Thanks for referring me to the Optar chart - the format of that chart data is just perfect! I will search as advised on filter size and see what else I can find, and how much other info can be collected in one easy-to-find place.

Welcome to the wild world of Graflex. I have a owned my Speed Graphic now for over a year and I am also completely hooked by the Graflex bug. I have a copy of Graphic Graflex Photography (1940) with some lens information including filter sizes for popular lenses for Graflex. Also I have some Kodak Lens guides from the 1950's which has filter information for Ektar lenses. I have spent the last few weeks scanning them, if you want I can send you the scans with the filter information. Send me an email and I can send you those files. Take care and have fun with your camera.

Thanks for the chart, Rich! Is it from a Graflex source? It's interesting as much for what it omits as what it includes. For example, no listings for the 65mm Optar or the 101mm Optar lenses! And I can't tell whether that 101 listed is "Graflar" or "Graftar," but my Graftar takes a 31.5mm slip-ring (same as the 101 Optar).

Rich, that is a killer chart! I agree with Henry, if you can ID the source that would be great info. In the meantime, I will "assimilate into the collective" %v)

So far I'm pulling together some good stuff, including relevant info from Graphic Graflex Photography, which shows which Series is needed for which size lens diameter. Ansel Adams' the negative also has some info worth including.

Henry, once all this great info is collected, how do I go about submitting it to Graflex.org?

Many thanks to all for your support, and please continue to share all this great stuff!

The chart is from a Graflex sales and pricing catalog from ~1964 -> 1967 or so. Many individual sections are not dated. There's a lot of good info in the assortment of sheets, but unfortunately nothing on the two specific pieces I was looking for... Just my luck

Just checked, the 101 is a Graflar and the sheet is dated from 1964. I think there's at least one other lens chart. I'll go looking for those other lenses...

It's interesting (curious?) that the chart, though presumably a Graflex document, lists neither the 65 nor the 105 Optars! The 65 takes a 33 mm slip-ring, though mine would not fit without modification, and the 105 of course takes the ever-popular 31.5 mm slip-ring.
